This paper is devoted to the effectiveness of the courts’ administrative control in Europe. The main thesis is that the effectiveness of control is not dependent on the competences in adjudicating the administrative cases. The competences both in cassation and reformation are diversified. Therefore the measures of enforcement are adapted to these competences. The effectiveness of the court administrative control is dependent on the compliance between the adjudication and enforcement competences. The more diverse the competences are, the greater is the chance for the enforcement of a judicial decision within a reasonable time.
